RAIN-WATER FILTER. 1

Specification of Letters .Patent.

Patented Mar. 2, 1915.

Application filed April 20, 1914. Serial No. 833,216.

The invention relates to improvements in 7 rain water filters. g

The object. of the present invention is to improve the construction of rain water filters and to provide a simple, practical, and eificient non-freezing rain water filter of strong, durable, and inexpensive construction, adapted to be easily cleaned and maintaine in a perfectly sanitary condition.

With these and other objects in view the invention consists in the; construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantagesof the invention.

In the drawing: Figure 1 is a vertical sectional view of a rain water filter con- In the accompanying drawing, in which is illustrated the preferred embodimentof theinvention, the filter comprises in its construction an outer casing 1, preferably of cylindrical form and constructed of galvanized sheet metal or other suitable masigned to have its outer portion connected to a suitable conduit 5," as illustrated in dotted lines in Fig. l ,of the drawing, for

conveying the filtered water to a cistern or other vreservoir (not shown). The bottom 2 is provided at the drain opening 3 with a depending threaded flange, and isequipped with a screw cap 6. When cleaning the filter,

the outlet a is closed by a cap or closure 7, which is placed on the upper end of the outlet, and when it is desired to drain off any water used in washing the filter, the screw cap 6 is removed. By this arrangement the outer casing may be thoroughly cleaned without any of the water used in cleaning passing out through the outlet 4 and entering the conduit 5.

The outer casing, which has a removable top or cover 8, is provided at the upper portion with an elbow pipe connection 9, designed tobe connected with a rain spout 10, or other pipe connection, as indicated in dotted lines in Fig. 1 of the drawing. The

inlet 9, formed by the elbow, is located a short distance below the top or cover, and the'water entering at the inlet 9 flows into an inner cylindrical casing 11 constructed of galvanized sheet metal or other suitable material, and preferably consisting of a cyl- T' inder, open at the top and bottom and supported upon the bottom of the outer casing.

The inner casing, which forms a receptacle for charcoal 12, or other suitable filteringmaterial, is provided withupper and,

lower horizontal screens 13 and 14:, spaced apart to form an intervening compartment for the filtering material. The lower screen 14: is permanently secured within the lower portion of the inner casing in spaced rela tion with the lower edge thereof, to leave a lower end space of chamber 15, which con stitutes a water compartment. The upper screen Jisadjustable'within the inner casing to enable it to: be fitted tightly against the charcoal for holding the same firmly in place. The upper screen is provided at its upper face with a reinforcing brace 16, consisting of a fiat bar, suitably secured to the screen. Centrally riveted or otherwise connected to the brace 16 is a locking bar 17 arranged at right angles to the brace and having upturned terminals 19'provided with slots 20 for the reception of bolts 21. The slot and bolt connection between the bar 17 and the inner casing enables the upper screen to be adjusted to clamp the charcoal and hold the same tightly against the lower screen. This is especially advantageouspas it enables the inner casing, with the filtering material, when removed, to be inverted for washing and cleaning, without displacing the Charcoal, which is thereby enabled to last longer than it would were it loosely placed'between the upper and lower screens. While the upper and lower screens or partitions are preferably constructed of woven wire, they may be made of any foraminous material. 7

The upper screen 13 is arranged in spaced relation with the upper edge of the inner casing, and the upper portion of the latter constitutes an open upper compartment or chamber 22 for the reception of a substantially cylindrical screen 23 consisting of a basket having a wovenwire body and provided with an imperforate bottom 24 of sheet metal or other suitable material. The

basket forms a receptacle for leaves or other thewoven wire body portion to provide an 7 intervening space between the bottom of the basket and the'filtering material. The imperforateibottom is adapted to distribute'the water which flows around the edges of the imperforate'bottom and through the space between the same and the upper screen 13,

I andthe said bottom 24 is adapted to pre:

vent a'constant drop of the water in the same place onthe filtering material.

The. lower open .end of the inner casing fits around the inwardly projecting portion of the outlet 4', and the said inner casing is equipped at its upper portion with a pivoted bail 25, to enable the inner receptacle and its contents to be conveniently lifted from the outer casing. The-pivoted bail isfoldable within the outer casing when the parts are assembled; In order to take care of any superfluousrain water, the inner casing is provided at the upper portion with a lateral is sufliciently larger than the inner, casing to permitthe lateral outlet to be readily inopposite side of the filter and interposed be tween the inner and outer casings and adapted to maintain the inner casing in proper position with relation to the inlet, so that the'raln water'will be delivered into the open upper end of the inner casing.

1 What is claimedis: i 1 A filter of the class described, including an outer casing having an upper inlet and provided with a substantially conical bottom having acentrally arranged drain a closure for the drain opening, cap

adaptedto be placed on the upper end of the outlet tube forclosing the same when cleaning the filter, and means removably arranged within the outer casing for holding filtering material. r

3. A filter of'the class described, including an 1 outer casing having an upper inlet and a lower outlet, an inner casing open at the top and bottom and'provided atpoints intermediate of its ends with spaced foraminous partitions forming a compart ment iorvthe reception of filtering material,

1 the lower partition being fixed and the upper partition being adjustable,- a' locking bar connected with the upper'partition, "and means for adjustably securing the termi-I a compartment for the reception of filter- J ing materialand' provided above the same with an open upper portion or' chamberarranged to'receive water from the said inlet, and a' removable open top receptacle 'arranged within the upper portion of the inner casing and having a portion of its exposed surface constructed of foraminous material to form'a screen and another portion of thesaid surface constructed of imperforate material to prevent a direct passage of the water therethrough; V

5.VA filter of the class described, including an outercasing' having an upper-inlet and a lower outlet, an inner casing having a compartment for the reception of filterling material and provided above the same 'withan open upper portion or chamber arranged to receive water from the said inlet,

and a removable open top receptacle arranged'withinthe upper portion of the in ner casing and composed of foraminous side walls and an imperforate bottom spaced from the lower edge of the body to" provide an intervening space between it and the bottom of the chamber. 1

6. A filter of the class described includopen at the top and bottomfand arranged within the outer casing in position to receive-water from the said inlet andhaving a chamber or compartment for the reception of filtering material spaced from the upper end of the inner casing to provide an upper chamber, said inner casing being provided at the upper portion below its upper edges with a lateral outlet communicating with the said upper chamber and extending through the outer casing to permit excess of water to escape from the said compartment without overflowing the top of the inner casing.

7. A filter of the class described including an outer casing having an upper inlet and a lower outlet and provided below the plane of the inlet with an opening, an inner casing open at the top and arranged within the outer casing to receive water from the inlet thereof and provided with a lateral outlet located below the upper edges of the inner casing to permit excess of Water to escape without overflowing the upper edges of the inner casing, the latter being also provided with means for holding filtering material and having an upper chamber with which the said outlet communicates, and a wedge interposed between the inner and outer casings for retaining the said lateral outlet in the opening of the outer casing.
